,1. Question 1: Biochemistry and Metabolism
Which of the following processes is primarily responsible
for the production of ATP in the cell?
- A) Glycolysis
- B) Electron transport chain
- C) Krebs cycle
- D) Fermentation
Correct Answer: B) Electron transport chain
Rationale: The electron transport chain is the final
stage of cellular respiration where the majority of ATP is
produced. It occurs in the mitochondria and involves a
series of protein complexes that generate a proton gradient
used by ATP synthase to synthesize ATP from ADP.
2. Question 2: Molecular Interactions
Which type of chemical bond is primarily responsible for
the secondary structure of proteins?
- A) Ionic bonds
- B) Hydrogen bonds
- C) Covalent bonds
- D) Disulfide bridges
, pleated sheets, which are the secondary structures in
proteins.
3. Question 3: Pharmacology
The therapeutic efficacy of a drug is determined at the
receptor level by which of the following factors?
- A) Affinity and intrinsic activity
- B) Protein binding and solubility
- C) Molecular weight
- D) Half-life and clearance
Correct Answer: A) Affinity and intrinsic activity
Rationale: The affinity of a drug describes how well it
binds to its receptor, while intrinsic activity refers to the
ability of a drug to produce a maximum response after
binding. Both are key in determining therapeutic efficacy.
4. Question 4: Acid-Base Balance
Which buffer system is the most important to maintaining
acid-base balance in human blood?
- A) Sulfate buffer system
- B) Phosphate buffer system
- C) Bicarbonate buffer system
- D) Protein buffer system
Correct Answer: C) Bicarbonate buffer system
Rationale: The bicarbonate buffer system is the primary
buffer system regulating blood pH, involving the reversible
reaction of carbonic acid and bicarbonate to maintain
equilibrium.
